You only need 100 amity. My recommendation is to just pop maximum amity buffs, refresh the conversation until you get an easy one such as "Talk Freely" and "Fail to spark interest 1 time". You will generally get somewhere between 1 - 10 amity each time and as long as you don't continue the conversation, you will accumulate the 100 amity you need.
Tip: Investing some energy into the Node helps with the game...a lil bit.
